The outbreak of yellow fever in Barcelona in 1821. The evolutionary origins of yellow fever are most likely African. [1] [2] Phylogenetic analyses indicate that the virus originated from East or Central Africa, with transmission between primates and humans, and spread from there to West Africa. [3]
The yellow fever epidemic occurred during late 1870, beginning in August to the end of the year. There were a total of 1235 deaths; 468 women and 767 men. [ 1 ] The epidemic ended due to the city following hygienic measures and the mosquitoes not surviving Barcelona's cold weather conditions in December 1870. [ 1 ]
Yellow fever virus. This disease is transmitted by the bite of female mosquito; the higher prevalence of transmission by Aedes aegypti has led to it being known as the Yellow Fever Mosquito. The transmission of yellow fever is entirely a matter of available habitat for vector mosquito and prevention such as mosquito netting. They mostly infect ...
There are more than 500 species of arboviruses, but in the 1930s only three were known to cause disease in humans: yellow fever virus, dengue virus and Pappataci fever virus. [202] More than 100 of such viruses are now known to cause human diseases including encephalitis. [203] Yellow fever is the most notorious disease caused by a flavivirus ...
Finlay's work, carried out during the 1870s, finally came to prominence in 1900. He was the first to theorize, in 1881, that a mosquito was a carrier, now known as a disease vector, of the organism causing yellow fever: a mosquito that bites a victim of the disease could subsequently bite and thereby infect a healthy person.

The first human virus to be identified was the yellow fever virus. [6] In 1881, Carlos Finlay (1833–1915), a Cuban physician, first conducted and published research that indicated that mosquitoes were carrying the cause of yellow fever, [7] a theory proved in 1900 by commission headed by Walter Reed (1851–1902).

Europeans suffered higher rates of death than did people of African descent when exposed to yellow fever in the Americas, as numerous epidemics swept the colonies and sugar plantations. [59] On the other hand, European exploration of tropical areas was aided by the New World discovery of quinine, the first effective treatment for malaria.
